| Artifact bias | A changed score, video, prompt, class plan, model, or rule stands for changed practice. | Name the artifact and any separate Method, capability, arrangement, Work, and effect claims. |
| Success-story bias | Failed or partial change Work is omitted. | Preserve stopped Work, actual outputs, unchanged or partly changed subject, and retry condition. |
| Stage-production bias | Concert, ballet, theatre, or festival production becomes the default local-change case. | Test social, paired, improvised, teaching, recorded, online, robotic, and low-resource cases. |
| Human-only bias | The performer, learner, observer, and practice-developing Agent are assumed to be one person. | Identify each Agent, supporting non-agent System, decision-bearing assignment, and Work attribution in human, robotic, AI, ensemble, and hybrid cases. |
| Metric bias | Technical improvement stands for artistic, bodily, partner, audience, or practice improvement. | Preserve non-equivalent observations, affected Systems, protected characteristics, and limits. |
| Authority bias | The best performer, teacher, founder, robot, platform, or audience is assumed to own the change. | Name the DecisionSubject, practice-developing Agent, authority, permission, consent, and the usable means by which an affected participant can refuse. |
| Cultural-control bias | One implementation is treated as style evolution. | Keep the later transmission, recognition, selection, retention, spread, and loss questions open. |
